I have discussed this with your team, but wanted to put an Idea post out there. Currently, Emma's Response API only includes the Mailing ID for the 'Delivered' type. We have a request out to Emma to include this on the other Response Types. However, I was wondering if it was possible to snag the Mailing ID from the API call itself as a work around. Since the calls are structured as: "/#accountid/response/#mailingid/[type], would it be possible to save the mailing_id used in the call and use that to surface the ID in the Emma Connector as a workaround in the meantime?
